Elevick: Are all 6CA7 Groove Tubes NOS tubes? In other woors, would you recommend any Grove Tube 6CA7 (in good condition, of course)?
Groove Tubes GT-6CA7-GE vs NO GE and NOS Sylvania
Anybody heard the difference between authentic NOS General Electric 6CA7's and the Groove Tubes GT-6CA7-GE? And what about the NOS Sylvania 6CA7's...how would they compare?
Any input is most welcome
